In the development of the automotive industry, the demand for plastic parts is increasing day by day, because the construction of automobiles has a very high degree of application of plastic parts, that is to say, the quality of plastic parts has a huge promotion effect on the development and construction of the automobile field, which requires plastic The production of parts requires quality assurance, and the quality of plastic parts is determined by the mold. Due to the things of the mold, there are not a few cases where the plastic parts produced in the application process cause losses in various fields, so the production of plastic parts It is very helpful for our economic development to conduct research with the purpose of improving the quality and efficiency of plastic parts.
